Detection of explosives via photolytic cleavage of nitroesters and nitramines.
The nitramine-containing explosive RDX and the nitroester-containing explosive PETN are shown to be susceptible to photofragmentation upon exposure to sunlight. Model compounds containing nitroester and nitramine moieties are also shown to fragment upon exposure to UV irradiation. The products of this photofragmentation are reactive, electrophilic NO(x) species, such as nitrous and nitric acid,...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولI2-catalyzed oxidative condensation of aldoses with diamines: synthesis of aldo-naphthimidazoles for carbohydrate analysis.
A novel method for the conversion of unprotected and unmodified aldoses to aldo-imidazoles has been developed. Using iodine as a catalyst in acetic acid solution, a series of mono- and oligosaccharides, including those containing carboxyl and acetamido groups, undergo an oxidative condensation reaction with aromatic vicinal diamines at room temperature to give the corresponding aldo-imidazole p...
متن کاملSynthesis and spectroscopic characterization of pyrrole-2,3- diones and their following reactions with 1,2-aromatic diamines
4-aroyl-5-aryl-2,3-furandiones and N,N-dialkyl urea combine with loss of water yielding the pyrrole2,3-dione derivatives in moderate yields (47-68%). Then, these compounds were converted into 2(1H)quinoxalinones with various 1,2-phenylenediamines. The structures and characterizations of the synthesized compounds were established by the Hand C-NMR, IR and elemental analysis.
